我已经失去了几个小时试图查明这个恼人的问题。我创建了一个简单的Java应用程序,它使用Jersey公开了一些REST服务。
在Eclipse中调试应用程序时,使用Tomcat 8服务器,一切正常。然后我将项目导出到WAR文件,将其部署到真正的Tomcat 8服务器,当我尝试调用REST服务时,我得到以下错误。我检查了一些显而易见的事情:确保我在服务器上使用正确的Java版本,确保包含库,......但是,唉,我被卡住了。

项目的所有重要库都添加在WEB-INF中,如下所示:
答案 0 :(得分:0)
我相信这不是因为缺少jar ..我相信它是类加载问题。未装载(或)装备的衣架罐可能装错了版本。您能否正确检查依赖关系,并在您的应用程序中检查重复的jersey jars。
另外请尝试取消部署应用程序并再次部署..这可能会删除已经为taht应用程序加载的所有类,而Tomcat可能会再次初始化类加载..
希望这有效......
